1 Claim.

This invention relates to electrical conductors,

particularly to a connector for conductors arranged at an angle to eachother.

The primary object is to provide a novel arrangement for connecting onepair of concentric conductors with another pair of concentric conductorswherein one pair is disposed at an angle to the other pair, whicharrangement is of simple yet sturdy construction and can be readilydisconnected.

With the above and other objects in view which will be apparent from thefollowing description to those skilled in the art to which the inventionappertains, the present inventionv consists in certain features ofconstruction and combinations of parts to be hereinafter described withreference to the accompanying drawing and then claimed.

In the drawing which illustrates a suitable embodiment of the invention:

Figure 1 is a side elevation of the conductors and connector; and

Figure 2 is a section through the arrangement of Figure 1, showing thesame in greater detail.

Referring to the accompanying drawing, the invention is illustrated asapplied to a vertical conductor I and a horizontal conductor 2. Thevertical conductor I is comprised of concentric current conductingelements 3 and 4 electrically insulated from each other by a sleeve 5 ofsuitable insulating material. The end of the outer element 4 isexternally threaded and the inner element 3 projects beyond the element4 and is similarly externally threaded.

Associated with the conductor I is a flanged sleeve member 6 containingan internally threaded extension member 1 which is electricallyinsulated by insulation Il and extends beyond the sleeve member 6. Theinner element 3 is threaded into the extension member 1 and the outerelement 4 is threaded into the sleeve member 6.

The horizontal conductor 2, like the conductor I is comprised ofconcentric tubular current conducting elements 8 and 8 electricallyinsulated from each other by an insulating sleeve I0.

The outer element 4 of the conductor I is electrically connected to theouter element 8 of the conductor 2 by the sleeve member 6 and an elbowmember II having its ends recessed to partially surround the sleevemember 6 and conducting element 9. The sleeve member 6 and element 9 aresecurely clamped within the recessed ends 0i the elbow member I I byrecessed caps I2. Screws I3 secure the caps I2 to the ends of the elbowmember and when tightened securely clamp the sleeve member 6 and element9 in good electrical contact with the elbow member I I.

Connection between the inner conducting elements 3 and 8 is aorded by aplug I4 threaded into the end of conducting element 8 and having arecessed end which receives the extension member 1. A recessed cap I5secured by screws I6 to the plug I4 clamps the extension member 1 ingood electrical engagement with the plug I4.

By removing the screws I3 and one cap member I2 and the screws I6 andcap member I5 the conductors I and 2 can be readily disconnected.

The arrangement described provides a simple and sturdy expedient forconnecting electrical conductors, particularly electrical conductorsarranged at an angle to each other and each comprising a pair ofconcentric tubular conducting elements.

This arrangement is particularly adaptable for use in high-frequencyinduction heating equipment wherein current is conducted from atransformer to a heating coil.

It is to be understood that various changes may be made in the detailedconstruction and arrangement of the parts described without departingfrom the spirit and substance of the invention the scope of which isdefined by the appended claim.

What is claimed is:

A pair of inner and outer concentric current conducting elements, meanselectrically insulating said elements from each other, a second pair ofinner and outer concentric current conducting elements arranged at anangle to the rst pair, means electrically insulating said second pair ofelements from each other, an electrical connector having recessed endportions partially surrounding said outer conducting elements, recessedcaps partially surrounding said outer conducting elements, meanssecuring said caps to said end portions in clamping relation about saidouter elements, one of said inner elements having an end portionprojecting beyond its concentric outer element into intersectingrelation with the axis of the other inner element, a second connectorextending from within said other inner element and having a recessed endportion partially surrounding said projecting end portion, a capsurrounding the remainder of said end portion, and means securing saidlast mentioned cap to said last mentioned end portion in clampingrelation about said end projecting end portion.
